  2. 21. Structure-Function Relationships of Pi Class Glutathione Transferase Studied by Protein Engineering

    Author : Usama M. Hegazy; Bengt Mannervik; Mikael Widersten; T. J. Mantle; Uppsala universitet; []
    Keywords : Biochemistry; Glutathione transferase; targeted chemical modification; lock-and-key motif; cooperativity; stucture-function relationship; protein engineering; unnatural amino acid; site-specific mutation; Biokemi;

    Abstract : The glutathione transferases (GSTs) represent a superfamily of dimeric proteins involved in cellular detoxication by catalyzing the nucleophilic addition of the reduced glutathione (GSH) to the hydrophobic electrophiles. The present work focuses on the functional role of the conserved structures of GSTP1-1. READ MORE

    Abstract : Adrenocortical cancer (ACC) is a rare disease that is often difficult to diagnose, and therefore often presents at an advanced stage. Various cytotoxic treatments have been tried with little success. Evaluation of new diagnostic methods and improvement of medical therapies are therefore crucial. READ MORE

  5. 23. PROTEIN FOLD SWITCHING IN COARSE-GRAINED MODELS

    Author : Christian Holzgräfe; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Holzgräfe; coarse-grained model; protein folding; evolution; fold switching;

    Abstract : Proteins carry out the instructions encoded in genes and are crucial for many important tasks in the living organism. Often the specific three dimensional structure, or fold, of a protein enables it to carry out a given task. READ MORE

  6. 24. Studies on spinach plastocyanin and mutants : Expression in Escherichia coli, folding and function

    Author : Mikael Ejdebäck; Örjan Hansson; Miguel A. De la Rosa; Göteborgs Universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; plastocyanin; electron transfer; copper; protein-protein interactions; protein expression; folding; site-directed mutagenesis; NMR; Naturvetenskap; Natural sciences;

    Abstract : Photosynthesis is a process in which photons from sunlight excite chlorophylls in the thylakoid membranes of plants, algae and cyanobacteria. The photo-oxidised reaction centre chlorophyll P700 is re-reduced by an electron transferred from the soluble, blue copper protein plastocyanin. READ MORE

  7. 25. The regulation of factor Va activity by activated protein C -Importance of the individual activated protein C cleavage sites in factor Va

    Author : Eva Norström; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; Hematologi; extracellular fluids; Haematology; activated protein C resistance; activated protein C; Blood coagulation; Factor V;

    Abstract : The subject of this thesis is the activated protein C (APC)-mediated inactivation of factor Va. The activated form of factor V (FVa) is a procoagulant cofactor for Factor Xa (FXa) in the conversion of prothrombin to thrombin. READ MORE
